Internal links & site structure

BeginnerDuration ~35 min hands-onTools Your site’s pages, Your published capstone page

Why this lesson

You built a good page. If nothing points to it, it’s an orphan — crawlers may never reach it and searchers can’t navigate to it, so all that work sits invisible. Internal links fix that, and they do more: they tell search engines how your pages relate, and they funnel authority from your established pages to the new one you want to rank. Internal linking is the most underused free lever in beginner SEO — it costs nothing, you fully control it, and it directly helps the page from your capstone get found and get stronger.

The explainer

What an internal link is. An internal link is a link from one page on your site to another page on your site (as opposed to a backlink, which comes from a different site — that’s 1.6). Every time you link from page A to page B, you do three useful things at once: you give crawlers a path to discover B, you signal that A and B are related, and you pass a share of A’s accumulated authority (sometimes called “link equity”) to B.

Site structure: the shape underneath. Good site structure is shallow and logical. Aim for any important page to be reachable from the homepage in about three clicks. A common, robust shape is the hub-and-spoke (or pillar-and-cluster): a broad “hub” page on a topic links out to specific “spoke” pages, and each spoke links back to the hub and to its siblings. This makes the topic legible to search engines and makes authority flow sensibly. You’ll formalize this as topic clusters in Level 2; for now, just make sure related pages actually link to each other.

Navigation and breadcrumbs. Your main navigation menu is itself a set of internal links and a strong signal of what matters — keep it clean and put your important sections in it. Breadcrumbs (the Home › Category › Page trail) both help users orient and give crawlers an extra, consistent set of links that reinforce your structure.

Anchor text: describe the destination. The anchor text is the visible, clickable words of a link. Make it descriptive — the words should tell a reader (and a search engine) what they’ll get. Link the phrase “our guide to flat-feet running shoes,” not “click here,” and not a naked URL. Descriptive anchors give the destination page context about what it’s relevant for. (For internal links you can be direct and keyword-relevant; the caution about over-optimized anchors applies mainly to backlinks, covered next.)

Point strong pages at the page you want to rank. Here’s the tactic that matters most for your capstone: find the pages on your site that are already established — your homepage, an older post that gets traffic — and add a relevant, well-anchored link from them to your new page. You’re handing your new page a share of authority it hasn’t earned yet, plus a discovery path. It’s the single fastest internal move to help a fresh page climb.

The whole idea in one line: a page’s neighbours matter. A great page with no internal links is a room with no doors. Give it doors — from the right rooms, with signs on them — and it gets found, understood, and strengthened.

Do it

1. Map your site: list your main pages and draw which ones link to which. Spot any orphans (pages nothing links to) — especially your capstone page.
2. Add internal links so every important page, including your capstone page, is reachable from the homepage in ~3 clicks.
3. Add at least two links from strong existing pages (homepage, a popular post) to your capstone page, with descriptive anchor text.
4. From the capstone page, link out to 2–3 related pages on your site (links should flow both ways).
5. Check your main navigation includes your important sections, and confirm breadcrumbs are on if your platform supports them.
6. Re-run URL Inspection on the capstone page — a newly-linked page often gets recrawled faster.
